High Compressive Strength Insulation Board

The compressive strength of the chosen thermal insulation should be enough to bear both dead and active loads imposed by the flat roof and its use.

High compressive strength insulation board.

Short term testing compressive behaviour bs en 826 2013 and. Since eps is lower cost per inch than xps and is available in a range of compressive strengths from 10 to 60 psi using it belowgrade and under slabs can save on insulation costs. Sizes and thermal properties celfort and foamular high density insulation boards are available in a variety of thicknesses and standard sizes. Compressive strengths from 30 psi to 100 psi 210 kpa to 690 kpa to meet the requirements of nearly every application.

The mechanical strength of eps varies with its density. Thermal resistance the long term design thermal resistance of. Moisture effective resistance against moisture mildew corrosion and rot. Xps boards have a closed cell structure.

Dupont highload xps insulation is designed to stand up to the demands of airport runways bridge abutments ice rinks and more. When identifying the compressive capabilities of an insulation material it undergoes two tests. The most important mechanical property of eps insulation and building products is its resistance to compressive stresses which increase as the density becomes higher. Using an unnecessarily high strength insulation you end up paying for something you don t really need.

High performance under high loads get the muscle to meet the high load applications and the insulative strength to work in low temperature applications. The raw polystyrene granules are extruded using carbon dioxide as a blowing agent. Extruded polystyrene xps is a high performance insulation material that offers a high compressive strength while being resilient to water penetration. High compressive strength resists damage from heavy loads.

Available in 40 60 and 100 psi compressive strengths. The product needs to offer sufficient compressive strength for the intended application and also be capable of withstanding any demands placed on it during installation.
